Abstract
In an injector used for an internal combustion engine, a favorable magnetic attraction force is obtained to reduce a controllable minimum injection amount of a fuel injection amount. In a fuel injection valve in which a fixed core and a moving element is contained inside a pipe-shaped member, and a coil and a yoke are provided on an outer side thereof, a space for placing the coil is placed so that an inner circumference length in a vertical section of the space becomes smaller than an outside diameter of the yoke, or a height of the space in an axial direction of the fixed core becomes smaller than a diameter of the fixed core.
